Abstract
Increasing awareness of walking-related issues leading to falls, particularly in older adults, has highlighted this important concern.Even though walking is a fundamental human movement, studying it is difficult because it involves intricate brain, nerve, and muscle coordination.Neurodegenerative disorders like Amyotrophic Lateral Sclerosis (ALS), Parkinson's disease (PD), and Huntington's disease (HD) are frequently associated with walking limitations, highlighting the critical need for precise diagnostic tools.This study employed a comprehensive approach, delving into the intricate examination of gait patterns in individuals with neurodegenerative disorders.We used ground reaction force (GRF) step data from the Physionet public database, which converted into the time-frequency domain using continuous wavelet transform (CWT).We applied feature extraction techniques to identify unique gait characteristics for each disorder.Our findings revealed significant differences in gait among neurodegenerative diseases, with Parkinson's disease exhibiting the highest variability, ALS showing less variability, and Huntington's disease falling in between.These results illustrate the complex nature of walking issues in neurodegenerative diseases, highlighting the necessity of specific diagnostic approaches.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
